Actually you skipped a major part of my argument. If the definition of a christian is someone who believes in the bible. Then by that sole argument everyone who lived before the bible was compiled is not a christian.

Also your argument about someone wanting to follow christ automatically believing in the bible is also not a solid one. One can believe in the main lines in the bible but believe that either the authors or translators were misstaken. Therefore the document can not be trusted and faith in the bible would be voided.

Having said that the bible makes many a reference itself on how it's not complete. So the bible can not be the Final word in scripture. It says so itself. If the bible is true then the bible is not the FINAL word on God. (I'm not saying that it's not true but at the very least it's not complete.)
